Title
(EN) ELECTRODES FOR MULTI-POINT IGNITION USING SINGLE OR MULTIPLE TRANSIENT PLASMA DISCHARGES
(FR) ÉLECTRODES POUR MULTIPOINT UTILISANT DES DÉCHARGES DE PLASMA À RÉGIME TRANSITOIRE UNIQUE OU MULTIPLE
Abstract
(EN) A device for providing ignition of a fuel-air mixture using a transient plasma discharge is provided. The device includes an anode coupled to receive a voltage; and a cathode disposed in proximity to the anode and coupled to a ground, wherein at least one of the anode and the cathode includes a protrusion that enhances an electric field formed between the anode and the cathode, the protrusion forming a sharp edge defining a plurality of points, each point forming a path of shortest distance between the anode and the cathode.
(FR) L'invention concerne un dispositif de fourniture d'un allumage d'un mélange combustible-air utilisant une décharge de plasma transitoire. Le dispositif comprend une anode couplée pour recevoir une tension; et une cathode disposée à proximité de l'anode et couplée à une masse, au moins l'une de l'anode et de la cathode comprenant une saillie qui améliore un champ électrique formé entre l'anode et la cathode, la saillie formant un bord aiguisé définissant une pluralité de points, chaque point formant un trajet de plus courte distance entre l'anode et la cathode.
